Incorporating Monitor Audio’s innovative, pivoting Inverted Dual Concentric (IDC) midrange/tweeter module and 8" RST C-CAM bass driver, the three-way CP-CT380IDC represents the highest level of new CP performance. The IDC module houses a 4" C-CAM inverted midrange driver surrounding a 25 mm C-CAM Gold Dome tweeter.



  • Pivoting module consisting of IDC midrange driver and Gold Dome tweeter.
  • C-CAM bass driver featuring Rigid Surface Technology (RST).
  • High overall efficiency.
  • High frequency level adjustment (+/-3 dB).
  • Midrange frequency level adjustment (+/-3 dB).
  • Boundary compensation controls.
  • Our innovative Tri-Grip fixing system is easier to install than conventional clamping schemes but provides three times the surface area and a better surface seal, maximising bass response and mid-range clarity.
  • Magnetic and easily removable steel grille.
  • Paint-able surface to blend with the living environment. Additional scrim material is provided for trouble free painting.
  • Airtight enclosure design, which protects each precision-engineered driver system against the damaging ingress of dust and dirt.
